This specification establishes requirements for dimensions and gaging of taper pipe threads used on threaded plastic pipe and fittings. The type of pipe threads are designated by specifying in sequence the nominal pipe size, number of threads per inch, and the thread series symbols as follows. For left-hand threads add LH to the designation, otherwise right-hand threads will be understood. Different physical properties of pipe threads such as form, dimensions, angle, truncation, height, sealing capacity, and tightness shall be in accordance with the requirements specified. The gages have two types which may be used to completely cover gage requirements: (1) master gages used to check working gages; and (2) working gages used to check threads during manufacture and for conformance inspection. Both external and internal taper threads shall be gaged.
